Viewing TCP and UDP information

Perform this procedure to view the TCP and UDP configuration information for IPv6.

Procedure

Enter Privileged EXEC mode:

enable
Display IPv6 TCP connection information:

show ipv6 tcp connections [vrf WORD<1–16> | vrfids WORD<0–512>]
Display IPv6 TCP listener information for the specified IPv6 address:

show ipv6 tcp listener [vrf WORD<1–16> | vrfids WORD<0–512>]
Display IPv6 TCP properties

show ipv6 tcp properties [vrf WORD<1–16> | vrfids WORD<0–512>]
Display IPv6 TCP statistics

show ipv6 tcp statistics [vrf WORD<1–16> | vrfids WORD<0–512>]
Display IPv6 UDP information:

show ipv6 udp endpoints [vrf WORD<1–16> | vrfids WORD<0–512>]
